Configuring Measurement Parameters
Set Mixing Ratio
Use the MIXRATIO command to set the mixing ratio of SF
6
and the
other gas.
MIXRATIO [ratio]
where
ratio = Amount of SF
6
in the measurement environment, range
0 ... 100%.
Example:
mixratio 50
MIX RATIO : 50.00 %
Set Molar Weight of Other Gas
Use the N2MOLW command to set the molar weight of the other gas
(not SF
6
) in the measurement environment.
N2MOLW [weight]
where
weight = Molar weight of the other gas in kg/mol. The default is
2.8013401e-02, which is the molar mass of N
2
.
Example:
n2molw
OTHER GAS MOLAR: 2.8013401e-02 kg/mol ?
Set Pressure Normalization Temperature
Use the PNORMT command to set the temperature that is used to
calculate the normalized pressure parameter.
PNORMT [t]
where
t = Temperature in Celsius, range -100 ... 100. The default is 20.
Example:
pnormt 20
P_NORM_T : 20.00 'C
